T 0 ctZZ whom it may concern.-

Be it known that I, MARsHALL J. llconss, of New York, in the county of New York and State of New York, have invented a new and Improved Combined Furnace and Hotater Stereotype-Casting Box, of which the follow ing is a specification.

Ileretofore the most popular method of drying the molds on the face of the type or form was by the use of live steam, wit-l1 its everleaking and expensive attachments used in connection with the chest of the drying-table or casting-box; and when steam was not accessible gas, gasoline, or coal-oil was generally substituted, and many seriously objected to the latter from the fact that the heat derived was what is termed dry, and if not supplied with care would result in serious injury to the type by overheating in the drying process. Even steam by a too great a head or heat would prove injurious; and in every instance the two main, most important, and expensive parts of a stereotype outfitviz., the castingbox and the furnace-were separated and used separate and apart for their respective purposes. However, this my last' improvement-the combination of the metal furnace and the casting-boX by the use of hot wateris undoubtedlya most excellent one, producing an economy, simplicity, and practicability to an extent never before obtained.

The object of my invention is to dispense with these separate appliances by utilizing the casting-box, which has a hollow bed or platen for the reception of water to be heated by the same furnace which melts the metal for general stereotyping purposes, as hereinafter described and claimed.

Reference is to be had to the accompanying drawing, forming a part of this specification,

in which similar letters of reference indicate corresponding parts.

The drawing represents a perspective view of my apparatus complete, showing the cast ing-box overthe furnace in full lines and withdrawn in dotted lines.

The furnace or meltingpot is designated by letter A and is of ordinary construction.

B is a railroad or suitably-con structed frame for the transportation of the casting-box 0, extending over and beyond the top of the furnace or melt-ingpot. The casting-box is composed of the upper and the lower lids. D is the trunnion of the same, having a wheel or slide to be easily pushed backward or forward on the frame over the furnace or pot for both mold-drying and casting purposes, as shown in the figure. For casting, the cast ing-box is simply pushed back from over the center of the furnace from its mold-drying position to the rear end of the frame, where it is readily swung in a vertical position for the pouring in of the melted metal, as shown in dotted lines in the figure.

E is the hollow bed or platen.

F is a funnel or reservoir attached to the same to hold and to convey by the use of pipes or suitable channels the water to be heated.

G is an exhaust-pipe to conveniently supply hot water when needed for other purposes, and also to empty the chest when desired.

By the consolidation, as shown, it will be seen that the most desirable result possible is obtained, and without any additional expense or trouble whatever, and there is nothing to get out of order.

The bottom of the casting-box and mold drying apparatus is a hollow chest on wheels or slide and is simply filled with water through a small funnel-reservoir attached, and in the drying process of the mold it is on its railroad-frame easily run over and allowed to rest over the top of the metal-pot of the furnace. and the same heat that is used in the melting of the metal answers every purpose for the mold-drying process. The hot water in the hollow chest of the castiugbox thus equalizes the heat under the form molded and being dried, and it is impossible to secure overheat or any injurious effects, and, as before described, after the mold has thus been dried, the casting-box can instantly be run off the furnace on its railroad-frame in the proper position for casting purposes by the various patented devices belonging to and forming a part of the outfit.

This simple device renders stereotyping a grand success in the hands of any print-er. The combined arrangement occupies but very little room and can be placed in any printingofiice where an ordinary stove-pipe can be run to a chimney or line, and wood as well as coal can be used, if so desired. For mold-drying purposes it dispenses entirely with expensive appliances, and also with the use of obnoxious gas, gasoline; coal-oil, steam, &c., and is' de-' void of any of the objectionable overheating or injurious effects as regards the use of such in connection with the type.

I am aware that a hollow platen or bed for stereotyping purposes has been employed for the use of steam or hot Water separate from the furnace and the frame, as described in. a patent issued to me February 7, 1882.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- MARSHALL J. HUGHES. \Vitnesses:
